I'm considering buying Dr Prius and wanted to know if this app is good to determine the life expectancy left on my 200k 2009 Prius hybrid battery. I want to do a 2500 road trip but wasn't sure if this car will break down on my long road trip. The Prius has been flawless since New. Only issue was inverter pump, tires, 12volt, oil changes and 1x brake job since New. I consider this car to be my most dependable car ever with very low maintenance. Android ?
